ADUM3153ARSZ

ADUM3153ARSZ is a 7-channel, SPIsolator™ digital isolator optimized for isolated serial peripheral interfaces (SPIs). Based on the Analog Devices, Inc., iCoupler® chip scale transformer technology, the low propagation delay in the CLK, MO/SI, MI/SO, and SS SPI bus signals support SPI clock rates of up to 17MHz. This isolator also provides three additional independent low-data rate isolation channels in three different channel direction combinations. It is approved by UL recognition per UL 1577, 3750V rms for 1 minute, CSA component acceptance notice 5A, VDE certificate of conformity, DIN V VDE V 0884-10 (VDE V 0884-10):2006-12, VIORM = 565V peak. It is used in applications such as industrial programmable logic controllers (PLCs), and sensor isolation.
